We cover the sanctuaries you can actually visit — El Rosario and Sierra Chincua in Michoacán, Piedra Herrada and the Valle de Bravo area in the State of Mexico — and the tours that go there. Every page answers one question: which tour, which sanctuary, when to go, what it costs.
Tour details, prices and ratings come from the tour pages on GetYourGuide, checked in the month shown at the top of each page. Fees, opening dates and colony sizes come from Mexican press reports and WWF México / CONANP figures; travel warnings from the US State Department and the UK Foreign Office. Each figure carries its source on the page. When a figure comes from a single source, we say so.
We earn a commission when you book through our links, at no extra cost to you. No operator pays to be listed or ranked, and weaker reviews and downsides are reported as plainly as the good ones. Spotted a mistake? Tell us through the contact page.
